I use a dedicated watch for counting down the start sequences in yacht racing. My previous watch broke a couple of days prior to a major regatta and needed a replacement fast. Ordered 1 day delivery with Amazon and the watch arrived in time. I have only used the watch for sailing count downs so can't speak for the rest of the functionality (I haven't even bothered to set the time on it). However the countdown function works fine if that feature is important to you. Plus the price is right and much cheaper than getting a Ronstan Start Watch or similar.
